MOVABLE PLATFORM FOR RAILWAY-STATIONS, a0.

EBPEGIIICATION forming part of Letters Patent No. 350,232, dated October5,1886.

Serial No. 191,792. (No model.)

To all whom, it may concern.-

Be it'known that I, MATTHEW G. CARS- WELL, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Movable Platforms for Railway-"Stations and other Purposes, of whichthe following is a specification.

On elevated railways the station-platforms are sometimes required to bearranged at a curved portion of the track, and in such case thestation-platform itself is'curved correspondat the station-platform,they will be approximately tangential to the curve thereof, and even ifthe sides of the cars come close to the edge of the platform at themiddle of the length of the ear the car-platforms will be considerablyremoved from the edge of the stationplatform, and accidents have beenfrequent by reason of persons falling or slipping down between thestation-platform and the ear-platforms.

An important object of my invention is to provide for bridging over orcovering the space between the car-platforms and the curved platform ofan elevated railway-station; but the invention is also applicable toother stationaryplatfor1i1s-such as wharves or docksand thestreet-platforms of stores or warehouses. 7

The invention consists, essentially, in the combination, with a fixedplatform, of a slipplemental platform arranged beneath the fixedplatform and movable inward and outward relatively thereto, so that thesupplemental. platform may project beyond the fixed platform, or bedrawn inward and sheathed or The invention also consists in thecombination, with a curved station-platform and a curved railway-trackadjacent thereto, ofa supplemental platform movable inward and outwardrelatively to the station-platform for bridging over the space betweenthe stationplatform and platform of a car. The movable plat-form, or anynumber of them, may be 0perated by a hand-lever and suitable rods oremployed, if desired, in order to project the movable platform outwardfrom the fixed platfixed platform.

form, or to aid in moving it outward from the In an elevated-railwayplatform the movable supplemental. platform will be provided with rodsor bars which are guided in the stringers or floor-beams of the fixedstation-platform. i

In the accompanying drawings, Figure 1 is aplan of a curvedstation-platform and a rail- Way-track,andca1s adjacent thereto, aportion of the flooring of the station-platform being removed to showthe, arrangement of the movable platform. Fig. 2is a side elevation ofthe track and station-platform, and Fig. 3 is a transverse section ofthe fixed and movable station-platforms upon a larger scale.

Similar letters of reference designate corresponding parts in theseveral figures.

A designates the fixed and curved stationplatform, the planks orfloorboards of which are supported on floor beams or stringers A, and Bdesignates a curved railway-track adjacent thereto.

O designates the cars of the train on the track, and it will be readilyunderstood that as the straight sides are approximately tangential tothe curve of the track and platform the platforms or ends of the carswill be considerably removed from the edge of the curved stationplatform, even though the middle of the car comes close to the edge ofthe platform.

t-he stationary platform A and the platform of the car, I employsupplemental platforms D,

two of which are here represented. These supplemental platforms aremovable inward and outward relatively to the fixed platform A,

- and their outer edges are beveled, so that they will approximately fitagainst the sides of the cars at the ends thereof.

As here represented, the movable platforms have bars or rods d, whichproject inward from- .tliem and are guided in the floor beamsorstringers A of the station-platform A, the fioor beams or stringersbeing notched or re- 'cessed to receive said bars or rods, and theplatform may be slotted, as represented at (1*, so as to receive pins orbolts e, which limit the movement of the platform inward and outward, asbest shown in Fig. 3. If desired, a

spring, f, may be applied to one of the bars or rods (Z, as best shownin Fig. 3, in order to project the movable or supplemental platform Doutward from the main fixed platform A, or to aid in producing suchoutward movement of the supplemental platform.

In order to move the movable platform D positively, I have represented ahand-lev er, 9,

which, by rods 5/, is connected with bell-crank levers 9*, one arm ofeach bell-crank lever 9 having connected with it a rod, 9, and the otherarm of each bell-crank lever g having'a connection with one ofthe barsor rods d of the supplemental or movable plat-form. In this way anydesired number of supplemental platforms may be moved inward and outwardrelatively to the fixed platform by means of a single hand-lever andconnections suitably arranged between the hand-lever and thesupplemental or movable platforms.

The supplemental or movable platforms D should not proj ectsufficientl ybeyond the fixed platform to cause the cars to strike fullagainst theiredges, and the outer edges of these supplemental platforms are beveled,as described, so that the cars, by acting on their beveled edges, maypush them inward if they have too great projection.

The supplemental or movable platforms provide for bridging the spacebetween the station or fixed platform A and the platforms of the ears 0,and prevent any accident from persons slipping or falling through thespace between the fixed platform and the ear-platforms. The supplementalor movable platforms slide inward and outward beneath the fixedstationary platform A, and when moved inward they are sheathed beneaththe fixed platform and no person can trip on their edges and fall.

The beveled outer edge of the movable platforms D may be provided withanti-friction rollers s, to prevent any injury to the car from rubbingon'the platform.

Vhat I claim as myinvention, and desire to secure by Letters Patent, is-

1. The combination, with a fixed platform, of a supplemental platformarranged beneath the fixed platform, and movable inward and outwardrelatively thereto, substantially as herein described.

2. The combination, with a curved stationplatform and a curvedrailway-track adjacent thereto, of a supplemental platform movableinward and outward relatively to the stationplatform for bridging thespace between the station-platform andtheplatform of a car,substantially as herein described.

3. The combination, with a fixed platform, of a supplemental platformmovable inward and outward relatively to the fixed platform, and a leverand connections whereby said supplemental platform may be operated,substantial] y as herein described 4:. The combination, with a fixedplatform, of a supplemental platform movable inward and outwardrelatively to the fixed platform, and a spring for projecting themovable plat form beyond the fixed plat-form, substantially as hereindescribed.

5. The combination, with a fixed and curved station-platform and'acurved railway track, of a supplemental platform movable inward andoutward relatively to the fixed platform,

and rods or bars supporting the supplemental i platform and guided inthe stringers or floorbeams of the stationary platform, substantially asherein described.

6. The combination, with a fixed and curved station-platform and acurved railway-track adjacent thereto, of a number of supplementalplatforms, movable toward and from the fixed platform for bridging overthe space between the station-platform and the car-platforms,

and a hand-lever and connections whereby the I MATTHE C. CARSVELL. V
